HEATER FOR HOT WATER OR STEAM.

SPECIFICATION forming part of Letters Patent No. 568,994, dated October 6, 1896.

Application filed May 1l, 1896.

Be it known that I, GEORGE TALBOT, of Lynn, county of Essex, State of Massachusetts, have invented an Improvement in Heaters for Hot Tater or Steam, of which the following description, in connection with the accompanying drawings, is aspecification, like letters on the drawings representing like parts.

This invention has for its object the production of an improved furnace for heating hot water or generating steam for heating purposes.

illy heater presents a fire-pot with double walls, leaving between them a water-chamber, the upper end of the lire-pot having connected inwardly-turned hollow spider-arms leading to an 4outlet through which the hot water or steam passes into a pressure-drum located above and joined to said spider, the periphery of the drum being shown as, eX- tended outwardly to present a diameter in excess of the external diam eter of the fire-pot, so that the casing, extended from the periphery of the drum downwardly to the top of the ash-pit, will leave a space between the fire-pot and the interior 0f the casing for the circulation of the products of combustion from the hre-pot, so that the ire-pot is heated internally and externally.

Figure l, in vertical section, shows a heater embodying my invention; and Fig. 2, a detail to be referred to.

The ash-pit A, composed of side walls a, bottom plate a', and top plate a?, and having a door a3, is and may be of any usual or suitable shape. The top plate has a central opening, in which is mounted a grate b, having a pivot-pin b and a series of cog-teeth b2 near its edge. The pivot b enters a socket or hole in a tipping-shaft b, provided with a handle b", by which to turn the shaft and tip the grate. One end of the shaft enters a sleeve c, properl y supported in bearings of the ash-pit frame, and has at its outer end a squared or other end, to be engaged by a handle by which to rotate the sleeve and cause the gear-teeth c at its inner end to engage the teeth b2 of the grate, to turn the same when desired to shake the coal, d'c. The top plate supports the fire-pot e, composed of a cylindrical hollow casting, its inner and outer walls being separated to contain water to be heated.

The upper end of the lire-pot has three connected inwardly-directed hollow spider-arms d', having, as shown, a common outlet d2 just above the central part of the fire-pot.

The fire-pot has near its top a space or notch di to enable the coal or other fuel to be put into the fire-box, and below said notch there is a space f for the insertion of a Slicer-bar. The outlet d3 has screwed into it a nipple g, which enters the pressure-drum g', having suitable outlets g2 in any desired numbers.

The water as it becomes heated in the lire- 'pot, which becomes a boiler, rises through the nipple and enters the drum, and from thence circulates through suitable pipes joined to the out-lets g2 and leading to the rooms to be heated.

If steam is to be used, the drum shown in full lines will be removed and a higher drum of greater capacity, partially represented by dotted lines, will be put in its place. Y

The drum is of greater diameter than the tire-pot, substantiallythe diameter of the ashpit, so that when the metallic casing h is applied from the periphery of the drum to the ash-pit a space h will be left all about the tire-pot, so that the products of combustion rising from the top of the fire-pot will, when the' main draft-damperL 'in is closed, as it will be except when the tire is first started, pass downwardly about the tire-pot and to the out let m and up the pipe or flue m2, out through the collar m3, connected bya suitable stovepipe with a chimney. between the casing and the notch as by a U-shaped plate n just below and extended upwardly at the sides of the feed-door n', and by a plate n2 just below the under sideof the The space 77,' is blocked pipe n3, containing the main damper ni on shaft m4. A

The drum shown by full lines is of sufficient size for hot-water circulation, but for steam circulation I remove the drum g' and putin place of it a deeper drum, to afford space for the steam.

The lower part of the tire-pot has at opposite sides a box o, (see Fig. 2 and dotted lines,

IOO

Fig. 1,) which extends to and Vthrough the casing h, the box` beingv ltapped fo receive the cold-Water or feed pipel p.

I may, if desired, add any desired number of drums, one above the other, connecting them by suitable nipples to insure circulation of the water or steam, Whichever is used.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a heater, a double- Wall or hollow fireboX, provided at its upper end with connected hollow spiders or arms, extended across the Tire-pot and having a common outlet, a drum of greater diameter than and mounted above said fire-pot and in communication with said combustion into said space, substantially as descrised.

In testimony whereof Ihave Signed my name to this specification in the presence of two subscribing witnesses.
